Description
Technical Field
The utility model relates to the technical field of valves, in particular to a fire signal gate valve.
Background
The fire signal butterfly valve reduces the connecting bolts of the valve body under the conditions of high pressure and large caliber, can enhance the reliability of the valve and can overcome the influence of the dead weight of the system on the normal operation of the valve. The special signal butterfly valve for fire control can clearly display the valve switch state, has the visual, clear and reliable function of reflecting the working state in the fire control system, and is widely and largely applicable to the fire control system.
The existing fire control signal butterfly valve can meet the requirements, but when the valve plate moves up to the upper cavity of the valve body, the upper cavity is communicated with the fluid channel of the valve body, so that water flows into the upper cavity. When the valve plate is closed and moved downwards, the fluid in the upper cavity cannot be discharged, so that a section of the valve rod in the upper valve cavity is always soaked in the fluid in the upper valve cavity, and the surface of the valve rod is easy to rust. Meanwhile, the inner wall of the upper cavity is easy to rust after being soaked all the time, and the service life of the valve is greatly reduced.
To solve this problem, the present utility model has been made.
Disclosure of utility model
Therefore, the utility model provides the fire control signal gate valve which has simple structure, can prevent the valve rod from being corroded and has long service life.
In order to solve the technical problems, the fire control signal gate valve comprises a valve body, a valve cover arranged on the valve body, a water inlet channel and a water outlet channel which are arranged on the valve body, a valve seat arranged between the water inlet channel and the water outlet channel, a valve plate for sealing the valve seat, and a connecting block, wherein a valve rod is rotationally arranged in the valve body, one end of the valve rod is connected with the valve plate, the other end of the valve rod penetrates out of the valve cover, the connecting block is sleeved on the valve rod, the connecting block and the valve rod are in threaded transmission, a limiting device for enabling the connecting block to do linear motion is arranged in the valve body, and an isolating device for isolating water flow from the connecting block to avoid entering the inner wall of an upper cavity when the connecting block is lifted up and down is further arranged between the connecting block and the valve body.
The isolating device is a stretchable telescopic tube, one end of the telescopic tube is sleeved on the connecting block, and the other end of the telescopic tube is arranged on the valve seat.
The limiting device comprises a limiting rod, wherein the limiting rod is arranged on the connecting block, a limiting channel is formed in the inner wall of the upper cavity of the valve body, and the limiting rod is arranged in the limiting channel.
The valve seat is provided with a drainage channel for draining water in the upper cavity after the valve plate seals the valve seat.
The water draining channel is internally provided with a one-way valve.
The improved structure is that the two ends of the drainage channel are provided with a first filter screen and a second filter screen which are used for preventing the check valve from being blocked.
By adopting the technical scheme, the utility model has the beneficial effects that:
Simple structure can prevent valve rod corrosion, and life is high. Through the sealing effect of flexible pipe for rivers can not flow into the intracavity portion, thereby avoid valve rod and last intracavity wall to bubble in water for a long time and lead to valve rod and last intracavity wall corrosion easily, be favorable to improving the life of valve.
Drawings

Fig. 2 is an enlarged schematic view of the embodiment a of the present utility model.
Detailed Description
The utility model will now be further described with reference to the drawings and specific examples.
Referring to fig. 1-2, the embodiment of the utility model discloses a fire signal gate valve, which comprises a valve body 1, a valve cover arranged on the valve body 1, a water inlet channel 2 and a water outlet channel 3 which are arranged on the valve body 1, a valve seat 5 arranged between the water inlet channel 2 and the water outlet channel 3, a valve plate 4 for sealing the valve seat 5, and a connecting block 7, wherein a valve rod 6 is rotationally arranged in the valve body 1, one end of the valve rod 6 is connected with the valve plate 4, the other end of the valve rod 6 penetrates out of the valve cover, the connecting block 7 is sleeved on the valve rod 6, the connecting block 7 and the valve rod 6 are in threaded transmission, a limit rod 8 is transversely arranged on the connecting block 7, the valve body 1 is positioned on the inner wall of an upper cavity and provided with a limit channel, and an isolating device for isolating water flow from entering the inner wall of the upper cavity when the connecting block 7 is lifted up and down is further arranged between the connecting block 7 and the valve body 1.
Preferably, the isolating device is a stretchable telescopic tube 9, one end of the telescopic tube 9 is sleeved on the connecting block 7, and the other end of the telescopic tube 9 is arranged on the valve seat 5.
When the gate valve is opened, the valve rod 6 is rotated, and the valve rod 6 drives the valve plate 4 to ascend. Simultaneously, valve rod 6 and connecting block 7 screw thread transmission for connecting block 7 makes progress, and flexible pipe 9 is upwards pulled to the time when connecting block 7 makes progress. At this time, the water flow of the water inlet channel 2 flows into the upper cavity from the valve seat 5, and the water flow cannot flow into the upper cavity due to the sealing effect of the telescopic pipe 9, so that the valve rod 6 and the inner wall of the upper cavity are prevented from being corroded due to the fact that the valve rod 6 and the inner wall of the upper cavity are soaked in water for a long time, and the service life of the valve is prolonged.
In order to remove the water in the upper cavity completely after the valve is closed, the valve seat 5 is provided with a drain channel 10 for removing the water in the upper cavity completely after the valve plate 4 seals the valve seat 5, and the water in the upper cavity is further rustproof.
In order to enable water to drain only to the drain passage 10, a one-way valve 11 is provided in the drain passage 10.
In order to prevent the check valve 11 from being blocked, a first filter screen 12 and a second filter screen 13 for preventing the check valve 11 from being blocked are arranged at two ends of the drainage channel 10.
While the basic principles and main features of the present utility model and advantages thereof have been shown and described, it will be understood by those skilled in the art that the present utility model is not limited by the foregoing embodiments, which are described merely by way of illustration of the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined in the appended claims and their equivalents.
